I'm trying to use the Transverse Mercator projection in ArcMap, but cannot seem to locate it in the coordinate system list.
I'm very new to GIS and ArcMap.
I'm going to try to use some data from OS Mastermap, which I believe is in the Transverse Mercator projection.
When I look at that projection, it looks very different to the one I get in ArcMap when I select WGS 1984 World Mercator, so I think I'm doing something wrong. I can't see Transverse Mercator in the coordinate system list either.
What I'm hoping for taken from wikipeia, what I have:
(And I think my datum is wrong as is is saying D_WGS_1984 and not OSGB36.)
How do I set up ArcMap to be in the Transverse Mercator projection?
